ST2ndUS7thDefinition & source ›
The share of this ZIP’s land area inside FEMA’s 1%-annual-chance floodplain — the “100-year” flood zone, where flooding has about a 1-in-100 chance in any given year.
Measured from FEMA’s mapped flood panels. Where a panel has not been mapped, no value is published for that ZIP — those ZIPs are absent from this comparison rather than counted as unexposed.
Full methodology ›Arsenic in groundwater
17.7%
in the top 7.8% nationally
Lower is healthier
ST81stUS92ndDefinition & source ›
The modeled probability that untreated groundwater in this area — the source private wells draw on — exceeds the federal arsenic limit of 10 micrograms per liter.
A modeled likelihood for untreated groundwater, the source drawn on by private wells, which are federally unregulated. It is not a measurement of treated water delivered by a public system, and it is not a test of any individual well.
Full methodology ›Colon-cancer screening

The estimated share of adults aged 45–75 who are up to date on colorectal-cancer screening.

ST1stUS4thDefinition & source ›
The modeled typical indoor radon level for this area, in picocuries per liter — the EPA recommends fixing a home at 4 pCi/L or above.
Modeled from indoor-radon measurements. In Alaska and Hawaii, where those measurements are not published, a US Geological Survey geologic radon-potential category stands in — a coarser input, disclosed rather than hidden.

Full methodology ›The read
Sullivan, New Hampshire (ZIP 03445), by its overall standing, sits in the top 13.6% healthiest ZIPs nationally (4,356th) and the top 39% of New Hampshire (95th).
Several good marks anchor the profile and deserve first mention: modeled tree cover registers in the top 3.1% nationally, and floodplain exposure stands in the bottom 7.4% nationally. Modeled extreme heat lands at the national minimum, shared with about 19% of ZIPs. Modeled colon screening is in the top 7.6% nationally, and homeownership resides in the top 10.7% nationally. Modeled radon rests in the bottom 4.3% nationally, and food insecurity lies in the bottom 11.6% nationally. Modeled tooth loss sits in the bottom 8.7% nationally. By contrast, modeled arsenic settles in the top 7.8% nationally, and distance to a community health center registers in the top 10.6% nationally.
Defined in plain terms, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Radon is a radioactive soil gas the EPA identifies as the top cause of lung cancer in nonsmokers. Floodplain exposure is land with about a 1-in-100 chance of flooding each year, nicknamed the "100-year floodplain". The nearest ZIP ranking healthier overall is ZIP 03450, about 1.0 miles away.

How these were chosen: only ZIPs with a published Score appear — a nearby ZIP with too little data to score won’t. Nearby means closest by distance between ZIP boundaries, which can cross state lines. A similar health profile is a close match across the nine Score domains, not similar demographics. Distances are measured between ZIP boundaries — ZIPs that touch share a border. How distance is measured

About the ± — it’s this estimate’s give-or-take (statisticians call it the standard error). The true life expectancy for this ZIP most likely falls within 1.55 years of 84.5, and it’s very unlikely to be off by more than twice that.

How these lists were built: they draw only from ZIPs that have a published Score, so ZIPs with too little data to score are not listed. Distance-based lists use distance between ZIP boundaries with no state filter, so an out-of-state ZIP can appear. Statistically similar means a close match across the nine Score domains, not a demographic match: the measure is the cosine similarity between two ZIPs’ domain scores, taken over the domains both ZIPs have data for and only where that overlap covers at least six of the nine — and where no ZIP clears that minimum-overlap floor, that list is left out rather than filled with a weak match.
